The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0028] As Figures 1 to 6 shown in the auxiliary positioning and laying felt cloth device for the beam area, which is arranged on the root platform and the tip platform of the blade, and includes: a reel 1, and bearings 2 are provided at both ends of the reel 1; two brackets 3, the two brackets 3 are arranged perpendicular to the reel 1 and are located at both ends of the reel 1; a bearing housing groove 4 is arranged at the top of the bracket 3; the bearing 2 is embedded in the bearing housing groove 4; wherein, a scale is provided on the outer circumference of the reel 1, and a stop block 5 is arranged on one side of the reel 1, a retaining edge block 6 is slidably arranged on the other side of the reel 1, a threaded hole 7 is provided on the outer circumference of the retaining edge block 6, a bolt is arranged therein, and an infrared device 8 is arranged on the retaining edge block 6.

[0029] The implementation process of the present utility model is to sleeved the bearings 2 on both ends of the unwinding shaft 1, and embed the bearings 2 into the bearing bush grooves 4. The edge stop blocks 6 and the stop blocks 5 are respectively arranged on both sides of the felt cloth. When performing the unwinding operation, first adjust the edge stop blocks 6. According to the devices at both ends of the blade tip and blade root, after positioning through the infrared device 8 on the edge stop blocks 6, lock it with the bolts in the threaded holes 7. Then, sleeved the sleeve with the felt cloth on the unwinding shaft 1, and press the stop block 5 against the other end of the sleeve and lock it. The unwinding shaft 1 starts to rotate and unwind under the action of the pulling force of the felt cloth. Since four layers need to be laid for the blade casting, when each layer of unwinding is completed, the unwinding shaft 1 can be directly taken out along the bearing bush groove 4 under the rolling of the bearings 2 for the replacement work of the next roll. The beneficial effects of the present utility model are that by setting scales and edge stop blocks on the unwinding shaft, the position can be flexibly adjusted according to the width of the felt cloth. The infrared device set on the edge stop blocks can ensure that there is no deviation during the felt laying process, guaranteeing the accuracy of felt laying. At the same time, the design of the bearing bush groove enables the unwinding shaft to be flexibly disassembled after the felt laying is completed.

[0030] In the present utility model, the edge stop block 6 includes a bushing 61 and a positioning ring 62. The bushing 61 and the positioning ring 62 are axially fixedly connected. The axial fixed connection between the bushing 61 and the positioning ring 62 enhances the overall structural stability of the edge stop block 6, enabling it to withstand greater forces and pressures, thereby ensuring the reliability and durability of the device during long-term use.

[0031] As a preference of the above embodiment, a plurality of through holes 621 are evenly spaced and arranged on the outer circumference of the positioning ring 62. The infrared device 8 is arranged in the through holes 621. The infrared device 8 is installed through the through holes 621, which can ensure its precise and stable position on the positioning ring 62, reduce the measurement error caused by the position deviation of the device, and improve the precision of laying the felt cloth. The evenly distributed design of the through holes 621 enables the infrared devices 8 to be evenly distributed on the positioning ring 62, so as to more comprehensively and accurately monitor the laying situation of the felt cloth, ensuring the straightness and accuracy of the laying.

[0032] In the present utility model, the stop block 5 is composed of two symmetric semi-circular fixing pieces, and is provided with connection holes 51 thereon. The design of the semi-circular fixing pieces makes the installation and disassembly process of the stop block 5 simple and fast. Without complex tools or operations, the installation or replacement of the stop block 5 can be quickly completed, improving the work efficiency. Through appropriate connection methods (such as bolts, nuts, etc.) and the design of the connection holes 51, it can be ensured that the stop block 5 remains stable and firm during use, and can prevent the stop block 5 from moving or falling off during the felt cloth laying process, ensuring the accuracy and safety of the laying.

[0033] In the present utility model, the bracket 3 is fixedly connected by a tension bar 9 provided in the middle. The tension bar 9, as a connecting member between the brackets 3, can effectively enhance the stability and rigidity of the entire bracket structure, resist the bending and deformation that the bracket 3 may generate when subjected to external forces, thereby ensuring the stability and reliability of the entire device during use; the position and quantity of the tension bar 9 can be adjusted as needed to adapt to bracket structures of different sizes and shapes.

[0034] In the present utility model, openings are provided on both the upper part of the bearing housing groove 4 and the side facing the unwinding shaft 1. On the side away from the unwinding shaft 1, a U-shaped baffle 10 with an upward opening is provided. The opening design of the upper part of the bearing housing groove 4 enables the bearing 2 to be smoothly inserted into the groove, which helps to ensure that the unwinding shaft always maintains an appropriate smooth state during the replacement process, reducing wear and friction.

[0035] As a preference of the above embodiment, the opening width of the U-shaped baffle 10 is smaller than the outer diameter of the bearing 2, which can effectively prevent the bearing 2 from falling out of the bearing housing groove 4 when rotating or being subjected to external forces. Since the opening width of the U-shaped baffle 10 is smaller than the outer diameter of the bearing 2, the bearing 2 is firmly stuck in the bearing housing groove 4, improving the safety and reliability of the entire device; by restricting the opening width of the U-shaped baffle 10, excessive shaking or displacement of the bearing 2 in the bearing housing groove 4 can be avoided, thereby maintaining the stability and precision of the entire device during operation. By providing a shaft fixing hole 11 at the end of the unwinding shaft 1 and connecting it to the outer side of the bearing 2, the connection strength between the unwinding shaft and the bearing can be further enhanced, which helps to improve the load-bearing capacity and impact resistance of the entire equipment and extend the service life of the equipment.

[0036] In the present utility model, a shaft fixing hole 11 is further provided on the outer side of the bearing 2 and at the end of the unwinding shaft 1. The shaft fixing hole 11 provides an additional fixing point for the bearing 2, enabling it to be more firmly installed on the unwinding shaft 1, which helps to reduce the shaking and displacement of the bearing during operation and ensure the stability and precision of the equipment operation.

[0037] Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
